Reliable Surge Protection for Electrical Systems
Surge protection devices help safeguard electrical installations by diverting transient surge currents and limiting the voltage that reaches connected equipment. Type 2 SPDs are commonly installed within low-voltage distribution systems to protect against transient overvoltages associated with indirect lightning activity and electrical switching events.
The ABB OVR T2 range is designed for coordinated surge protection within electrical installations. The OVR T2 N 80-350 C QS provides high-capacity neutral-to-earth protection and its replaceable cartridge design allows the protection element to be serviced without replacing the complete surge protection assembly.
Typical Applications
- Low-voltage electrical distribution systems.
- Industrial electrical control and distribution panels.
- Commercial building electrical installations.
- TT and TN-S distribution networks.
- Protection against indirect lightning-induced surges.
- Protection against electrical switching transients.
- Coordinated surge protection systems using ABB OVR devices.
